So it definitely works!  Quickly  removes cooking odours and clears the air!  Good value as steel grates and lights are included.  Was looking at various models and these features were extra.  Fairly easy install for a non handy family like ours.  It’s is noisy but I haven’t found anything comparable in terms of quality and looks with this much power.  Have had it up for a few weeks-hopefully this will last longer than our last one( different brand from appliance store)
